AI Technical Summary
Variable frequency rolling rotor compressors have a high oil output rate when operating at high frequency. When refrigeration oil enters the system, it reduces the heat exchange performance and leads to early oil shortage and wear of the compressor.
Design a floating component, including a floating part and a limiting part. The centrifugal force of crankshaft rotation and the buoyancy of oil create an oil passage with a variable flow area between the floating part and the limiting part, which adaptively adjusts the oil suction volume to meet the oil demand at different frequencies.
The compressor adaptively adjusts the oil suction volume at different frequencies to avoid oil shortage, improve oil suction efficiency, ensure smooth exhaust during high and low frequency operation, reduce the amount of refrigerant entering the oil sump, and improve compressor reliability and performance.
